This paper examined temporal changes in self-esteem among middle school students in Japan from 1989 to 2002. Previous research showed that self-esteem decreased among middle school students between 1999 and 2006. However, it was unclear whether such a decrease was also present in other periods of time. To obtain a better understanding of how people adapt to socio-economic environments, it is important to gain a more comprehensive view of such long-term cultural/social changes. Therefore, to supplement the findings of the existing research on changes in self-esteem, we analyzed large-sample time-series data collected in Japan in 1989 and 2002. We found that middle schoolers’ self-esteem decreased from 1989 to 2002, consistent with previous research. Thus, our study extends the previous research by presenting additional data showing the decrease in self-esteem in Japan.
